Definitions
- the deployment behavior of a gas cushion in a motor vehicle is usually intended for a situation in which the vehicle driver or a passenger from the seat belts held against the back of the seat is ajar, so a certain distance to yourself in a crash situation has deploying airbag and usually in the already inflated gas cushion falls.
- This so-called out-of-position (OoP) situation has already led to more serious injuries as she was alone by the actual impact without gas cushion would be done. Therefore, concepts have already been developed which detect the deployment behavior of the gas cushion and at an obstacle in the deployment area of the gas cushion, which leads to a diminished or even inhibited development leads, prevent further inflation of the gas cushion.
- the generic DE 199 13 095 A1 discloses a device with a gas inflatable by a filling device Gas cushion and a transmitting / receiving device for electromagnetic Waves and one associated with this Evaluation device, wherein at least one of the gas cushion Polling units is arranged by the transmitting / receiving device can be queried without contact and thus in the evaluation device information about the degree of development and / or the deployment speed of the gas bag are provided.
- the interrogation unit is characterized by a reflective Layer formed on the inside of the airbag, provides and reflects a light beam from a light emitter to a light receiver.
- the received light intensity is dependent on the degree of deployment of the airbag.
- the object of the present invention is therefore a device specify the above type, these problems avoids.
- the device according to the invention is provided with a transmitting / receiving device designed for electromagnetic waves, preferably in the dashboard of a device arranged vehicle is arranged.
- the transmitting / receiving device sends electromagnetic waves to one or more on the gas cushion arranged interrogation units, the in turn, a characterizing a respective query unit Return wave received by the transceiver and from one connected to the transceiver unit Evaluation device is processed and evaluated or be an appropriate response to the unfolding behavior to bring the gas cushion.
- the deployment speed can be relatively simple and nevertheless accurate and very easily reproducible way from the Doppler shift coming from the query units Waves are determined.
- An interrogation unit is according to claim 1 with a polarizing, preferably circularly polarizing reflector educated. When opposing polarizations are selected can already distinguish between two query units become.
- these according to claim 2 form as a transponder, so as units that receive the wave coming from the transceiver, at least part of their energy as supply energy to supply a logic circuit store and a encoded so with a code modulated wave send back.
- the logic circuit can in the simplest way as a switch be formed, the only one transmitting / receiving antenna turns on or off according to a stored code.
- a more complicated logic circuit is also conceivable, which allows a correspondingly more complicated coding.
- the logic circuit with a Be formed oscillator which actively generates a signal that upon excitation by a signal or a wave from the transceiver as a wave to the transmitting / receiving device is backblasted.
- different modulations at the same frequency or something similar. It is essential, anyway the signals of the individual interrogation units from the transmitter / receiver device can be distinguished.
- the figure shows a schematic cross-sectional view of a Vehicle cockpits with a seat 1 and a seated on it Person 2.
- An inflated gas cushion 3 is with a Number of query units 4 formed as a simple Reflectors or can be designed as a transponder. information Suitable transponders can be used on the website "http://rapidttp.com/transponder/".
- a transmitting / receiving device 5, with an evaluation (8) transmits electromagnetic waves 6 to the interrogation units 4. These send suitably coded Waves 7, which from the transmitting / receiving device. 5 received and processed by the evaluation device (8) become.
